RT series annealing (normalizing) furnace adopts full electric heating method. Lt is a kind of furnace superior to the furnaces like bell furnace, pushrod furnace, etc, This furnace (production line) adopts rapid annealing new technology and innovated technology, has the advantages such as compact structure, precise temperature control,simple and convenient operation, reliable running, low energy consumption, meeting to the requirements of environment protection, annealing quality surpassing the standard JB/T1255-2001, etc. Lt realized the goal of high efficiency, high quality, low energy consumption, continuous production in spheroidal anneal. On the basis of RT series furnace we produced patented products PRT Series Parallel Waste Heat Recovering Continual Annealing (normalizing) Furnace and BPT Series U-shaped Waste Heat Recovering Continual Annealing (Normalizing) Furnace. The energy consumptions of these two products are only two third of that of the RT series furnaces, half of that of the bell furnace and pushrod furnace. They are a kind of high efficient energy-saving furnace filing a gap in heat treatment equipments in our country, are really green heat treatment equipments. This kind of furnace is suitable for the continual annealing (normalizing) of bearing ring, hardware, steel pipes,bars, coiled bar, strip steel, iron shot, alloy tool steel, etc., is widely used for the preheating treatment of the precision forging, cold rolling, cold rolling, cold expansion parts.
